Classification apparatus for moving image data based on user interaction
A recently filed patent (Publication Number: US20230315783A1) describes a classification apparatus that utilizes a combination of hardware and software components to classify moving image data. The apparatus includes at least one memory for storing instructions and at least one processor for executing these instructions.
The apparatus first extracts moving image data using a predetermined rule. It then displays an icon on a screen of a display unit that corresponds to the extracted moving image data. The apparatus is capable of receiving user input and detecting movements of the icon on the screen caused by the user's operations. Based on the position of the icon on the screen, the apparatus specifies a classification for the moving image data.
In addition to these functionalities, the apparatus can also learn the weight of each feature information generated from the moving image data. It generates multiple feature information from the extracted moving image data and calculates a score for the data using the generated feature information and previously learned weights. The icon is then placed on the screen at a position corresponding to the calculated score.
Furthermore, the apparatus can relearn the weights of each feature information upon detecting movement of the icon on the screen. It recalculates the score for the extracted moving image data using the relearned weights and rearranges the icon on the screen accordingly.
The predetermined rule used for extracting the moving image data can be specified by the user. The apparatus can display visual information representing the condition used for extraction on the screen. Additionally, when the icon is selected by the user, the apparatus can play back the corresponding moving image data, display sensor information at the time of shooting, and show the location on a time axis where the moving image data meets the extraction condition.
The apparatus also allows the user to display the position of the icon corresponding to the weights before relearning. It can output moving image data corresponding to an icon located within a selected range on the screen.
Overall, this patent describes a classification apparatus that utilizes various techniques to extract, classify, and display moving image data based on user input and predetermined rules.
